State Emergency Service (SES) crews are still searching for a car swept into floodwaters at Denison Creek at Nebo, west of Mackay in north Queensland, at about 2am (AEST) today.

They do not know how many people were in the car but no-one has been reported missing to police in the region.

Police believe the motorist drove past other cars waiting by the road for the creek to subside.

Police divers will use sonar equipment when they search the creek tomorrow.

Damage bill

The damage bill from flooding in parts of Queensland has already hit $150 million but that figure does not include crop losses and property damage.

There are 11 council areas in central and southern Queensland that are eligible for natural disaster relief payments where farmers are reporting damage to wheat and cotton crops, and delays in getting cattle to market.

Premier Anna Bligh says it has been an early, and costly, start to the wet season.

"We've got more rain on the way," she said.

"We know that early estimates indicate we've seen at least about $150 million worth of damage to roads and other social infrastructure so it's very early in the summer to be seeing these kinds of floods."

Flood wise website

Brisbane residents are being urged to consider the City Council's Flood Wise report during the wet season.

The online service gives residents information about the potential flood threat to every property in Brisbane.

"There are many who have come to the city in the last 10 to 15 years that've been very, very dry years," he said.

"They don't appreciate that some of our idyllic suburban creeks can suddenly turn into raging torrents or there can be a huge amount of water that can flow down hillsides through the back of suburbia, through backyards causing a lot of damage to properties."
